Don’t ever use Drano and then call a plumber either (or at least tell them if you did) because it barely works and instead just sits in the pipe which then gets all over their skin and clothes as they try to remove the clog the proper way.

A youtuber I watch who cleans drains had this happen and he showed what his pants looked like the next day. They were essentially shredded all down the front from kneeling in Drano water.
